ON DYNAMICS OF THE BOHAI BAY COMPLEX FAULTED BASIN

Bahai Bay Basin,formed during the Meso-Cenozoic,is a typical complex faulted basin in eastern China.Based on the tectonic framework,structural style,tectonic transport and deep geophysical data of the basin,its dynamics was discussed.It was suggested that formation and evolution of the basin was resulted from superimposition and compounding of two dynamic systems in time and space,which were relative independent and co-exist in space.One was regional extension system trending NW-SE and another was N-S trending pull apart or strike-slip system resulted from Tanlu fault zone.
